Three composite laminate systems were produced using the standard hand lay-up method: jute-fibre-reinforced polymer (JFRP), carbon-fibre-reinforced polymer (CFRP) and a hybrid of the jute- and carbon-fibre-reinforced polymer (J/CFRP). The hybrid arrangement aimed to combine the stiffness and strength of carbon fibres with the toughness and energy absorption ability of jute fibres. Mechanical tests showed that the hybrid J/CFRP laminate had significantly higher tensile strength and impact resistance than the JFRP composites made from natural fibres only. This proves that fibre hybridization promotes interfacial load transfer and delays premature fibre pull-out. Drilling tests were performed on three laminate samples using an 8 mm TiN-coated, high-speed steel drill bit. The tests were conducted at three spindle speeds (600, 800 and 1200 rpm) and two feed rates (0.015 and 0.030 mm rev-1). The mechanical tests showed that the JFRP laminate had lower strengths (88 MPa tensile and 102 MPa flexural) due to weak interfacial bonding, whereas the CFRP laminate recorded the highest tensile and flexural strengths (215 and 246 MPa). At a perfect spindle speed of 600 rpm and a feed rate of 0.015 mm rev-1, the hybrid J/CFRP laminate exhibited a significant breakthrough, recording a tensile strength of 184 MPa, a flexural strength of 200 MPa and a reduced drilling-induced delamination, thus proving the beneficial synergistic effect of fibre hybridization.
